解决方法是什么？

Answer 1

您是如何安装 Python 的？如果您手动构建它或使用 make 命令，您可能会缺少 bz2 库 headers.

尝试以下...

Centos/Fedora/RHEL:

sudo yum install bzip2-devel

Debian 和 Ubuntu:

sudo apt-get install libbz2-dev

然后您需要重建 Python 安装或将 header 复制到 Python 文件夹中，其中：

sudo cp /usr/lib/python3.7/lib-dynload/_bz2.cpython-38-x86_64-linux-gnu.so  /usr/local/lib/python3.7/
